Funny Error on my PIII computer

Hello my friends at this forum.
Please don’t laugh or else I will become angry with you because the affected computer is Pentium III, running Windows 2000 PRO SP4 with 256MB of RAM. It’s not my fault, it is something done by Microsoft.
Today, I faced one of the funniest errors in history, while trying to install a trial pack of Office 2010.
The error says,

Error Error
An error occurred while displaying the previous error.
Although this is something funny, I'm still cautious about it, as I think something is wrong with my Windows error reporting system. This might be preventing Windows from telling me about the errors in future. So I want to solve it.
Your help is required for the same.
Thanks.
